SPECIFICATION forming part of Letters Patent N0. 730,716, dated June 9, 1903. Application filed December 16, 1902. Serial No. 135.428. (No model.)

To all whom it may concern:

Beit known that LGEORGE A. STILES, a citizen of the United States, residing at Somerville, in the county ofll/Iiddlesex and State of Massachusetts, have invented new and useful Improvements in Eyeglasses, of which the following is a specification.

My invention relates to eyeglasses; and the object of the same-is to constructa nose-bridge having simple and efficient means for limiting the grip of the jaws and adjusting the spread thereof. In nose-pieces as usually constructed the spread of the jaws is varied by bending the curved spring-bridge for operating the jaws. This method is very unsatisfactory, for the spring becomes bent by accident and the jaws either grip the nose so hard as to cause soreness or they permit the glasses to fall off. They also continue to bite in after having obtained a hold. My invention obviates both of these objections.

The simple and novel construction employed by me in carrying out my invention is fully described and claimed in this specification and illustrated in the accompanying drawings, forming a part thereof, in which-- Figure l is a rear elevation of my glasses. Fig. 2 is a detail elevation of the bridge, the parts being separated. Fig. 3 is a plan view of the cross-bar. Fig. 4: is a plan view of the stop-bars. Fig. 5 is a perspective of one of the stop-bars. Fig. 6 is a detail of one of the side bars.

Like numerals of reference designate like parts in the different views of the drawings.

The numeral 1 designates a pairof eyeglasses having lenses 2 and frames 3, connected to said lenses. A nose-bridge 4 connects the frames 3 and comprises two side members 5 and a resilient cross-bar 6, spanning the interval between the upper ends of said member 5 and firmly secured by screws 6, fitting apertures 6". The side members 5 are rigidly connected at their lower ends to lugs 7, formed on the frames 3, and have parallel guides 8 formed on their upper ends to accommodate the cross-bar 6, and two stopbars 9, mounted in said guides 8 and having their inner opposed ends 10 turned at right angles to abut and form stops to hold the cross-bar 6 bowed. A pair of serrated jaws 11 are supported by downwardly and rearwardly extending curved arms 12, which are rigidlysecured to the .lugs 7 by screws 12 and held against turning by guides 13, formed on said lugs. The cross-bar 6 is' made of stiff resilient metal and is initially straight, but when secured to the side members 5 the stops 10 are set so that when in contact the bar 6 is bowed slightly upward. The bars 9 can also be mounted on top of the bar 6 and the bar 6 bowed downwardly.

Instead of fixing the bar 6 to the side members 5 I may make them adjustable, so as to enable the glasses to be fitted to differentshaped noses; but in general itis preferable to substitute a different length of cross-bar instead of using an adjustment.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isv 1. In a pair of eyeglasses, the combination with two frames for lenses, of a bridge comprising two side members each connected at one end to said frames, a resilient cross-bar connecting the other ends of said side members, and stop-bars mounted in contact with said cross-bar and having their ends turned at right angles to form stops, substantially as described.

2. In a pair of eyeglasses, the combination with two frames for lenses, of a nose-bridge comprising two side members each connected to one of said frames, a resilient normally straight cross-bar connected to said side members, and stop-bars mounted parallel with and in contact with said cross-bar and having their opposed ends turned at an angle to abut and formstops, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE A. STILES.
